I think one of the parentheses is misplaced in file kern_lwp.c
function  proc_representative_lwp().

	case SACTIVE:
		/* Pick the most live LWP */
		onproc = running = sleeping = stopped = suspended = NULL;
		LIST_FOREACH(l, &p->p_lwps, l_sibling) {
			switch (l->l_stat) {
			case LSONPROC:
				onproc = l;
				break;
			    ......SNIP.....
			case LSSUSPENDED:
				suspended = l;
				break;
			}
			if (onproc)
				return onproc;
			     .....SNIP......
			if (suspended)
				return suspended;
------------>	}
		break;

Should probably read:

	case SACTIVE:
		/* Pick the most live LWP */
		onproc = running = sleeping = stopped = suspended = NULL;
		LIST_FOREACH(l, &p->p_lwps, l_sibling) {
			switch (l->l_stat) {
			case LSONPROC:
				onproc = l;
				break;
			    ......SNIP.....
			case LSSUSPENDED:
				suspended = l;
				break;
			}
------------->	}
		if (onproc)
			return onproc;
	        .....SNIP......
		if (suspended)
			return suspended;
		
		break;
